Abstract

The invention provides a fuzzy control method and apparatus for a signal receiving part in a high speed WDM system, wherein, the method comprises the following steps: step A, obtaining related information of each device in a receiving system and working environment parameter information of the receiving system; step B, according to the related information of each device and the working environment parameter information, finding out fuzzy control parameters which best match the related information of each device and the working environment parameter information from a fuzzy control parameter table stored in the system, and controlling the parameters of each device in the receiving system according to the fuzzy control parameters to make the system reach the best receiving balancing point. The invention can simplify the adjusting steps of the receiver and save the adjusting time.

Description

TECHNICAL FIELD[0001]The present invention relates to the field of optical communication technology, and in particular, to a fuzzy control method and apparatus for signal receiving part in high speed Wavelength Division Multiplexing (WDM) system.BACKGROUND OF THE RELATED ART[0002]With the evolving and developing of the conventional Dense Wavelength Division Multiplexing (DWDM) optical transmission system, the transmission with higher speed (>40 Gbit / s) implemented in a single channel has become a clearer direction for the evolution thereof. In the evolution direction, an important technology is the high speed optical signal processing at the receiving end of the channel, i.e. how to transform efficiently the high speed optical signal into the information which is recognizable by the receiving chip. Wherein, the following technologies may be involved:[0003]1. since the dispersion tolerance of the high speed transmission system is exponentially reduced, more accurate channel disper...
